An efficient, environmentally benign and unprecedented synthesis of various α-sulfenylated amides/esters has been developed under oxygen atmosphere. The reaction shows good functional group tolerance and excellent chemo/regioselectivity. All the desired products were obtained in moderate to excellent yields, even on the gram scale. Practically, the related α-thiol Weinreb amide can be readily transferred
在氧气气氛下,已经开发出一种高效,环境友好的和前所未有的合成各种α-亚磺酰化酰胺/酯的方法。该反应显示出良好的官能团耐受性和优异的化学/区域选择性。即使在克规模上,也以中等至极好的收率获得了所有所需的产品。实际上,相关的α-硫醇Weinreb酰胺可以很容易地转移到一系列预期的化合物中,并且硒原子可以高产率地引入到酰胺的α-位。
